Ways to design a Minecraft birthday banner include printing the free template from The Party Animal site onto card stock or using the Quality Kids Crafts site to print out messages on card stock and then adding Minecraft imagery to the letters. Each method requires scissors, hole punch and string.
The Party Animal site provides a free template for a printable Minecraft birthday banner. For both appearance and sturdiness, the site recommends printing the template onto card stock and then laminating it. The template prints out the words "happy birthday" with each pixellated letter separate and with Minecraft creepers bookending each side. After printing and optionally laminating each letter, use the hole punch to put holes in the upper left and upper right of each letter. The final step is to run the string through the holes and hang the banner up.
Another method is using the Quality Kids Crafts site to create a custom message. This message can then be printed onto card stock and cut into the desired letters. To give the message a Minecraft theme, print out a Minecraft digital paper pack from sites such as HaleGrafx. Afterwards, use scissors to make the printed paper pack patterns match the printed letters and then adhere them to each other with spray adhesive.
